This is what a hijack may look like. Where you search for your domain, but someone else takes over the result.

Moderator, Ian Mcanerin, explains:

Hotfrog appears to link to websites using a redirection script issuing a 302 redirect. For new/low ranking sites, this can result in what is called a "hijack".

This can happen because a 302 actually tells a search engine that the original site is HotFrog and that it has been temporarily moved to your URL. Accordingly, the search engine shows the "original" if it has enough link juice.

This won't happen once you have enough links to outrank the page that it's on, but right now, it can be a real issue. It's one of the very few times when someone else can harm your site.

So he warns new site owners to "NEVER submit to a directory that uses 302 redirects for click tracking."
